In the accompanying drawings, 1 represents the gearend standard or frame 'of the machine, and 2 lrepresents the oppositev or l what might be termed rear end standaard,

and are for the purpose motion to the screw threaded shafts 14 and 4l5.

v centric with each other,

ship and in proper erence to each other by means of the groovedV .tie-b'ars 3 and 4,. 'Between the groovedtiebars 3 and 4 'at their gear ends 1s inserted the which standardsare held in space-d relationparallel position with refplate and thel tie-bars provided with curved arts 6 and 7, which curved-parts are securely olted or otherwise attached to the standard 1. The standard 1 is provided with the lateralv arm 8', Awhich lateral' arm is for the purpose of roviding a means for locating a suitable hearing for the outer end of the power shaft 9, to which vpowershaft is attached-the usual reversepulleys 10, said pulleys `beingof the usual construction wherein 'itjis desired to reverse the motion of a machine by, belt pulleys. common and needs no specific description This construction is here. To the shaft 9 is securely attached the gear wheel 11', which gear wheel is located intermediate the gear wheels 12l and 13, said connected to the afnd 15 respectively o imparting rotary gear wheels being securely screw threaded shafts 14 The'gear'wheel 11 is interposed for the purpose of causing the gear wheels 11 and 12 to rotate in the same direction, therebygiving a vone direction movement to the two screw threaded shafts 14 and 15. The tievbars 3 and 4 are each providedfwith the grooves 16 and 17 which grooves receiverthe ribs 18 an 19, which ribs are preferably formed integral with the blocks 20 and 21.

`To the blocks 20v and 21 is attached, by

means of bolts'or thelr equivalents the head 22 which head consists of the outer and inner integral rings 23 and 24, which rings are conand are tied together by the integral `bars'25, which bars are extended and connected to the main-bod of the head 22. The object of' forming the ars is simply to lightening the structure, as it wil be vunderstood that the same object and urpose could be carried out if instead of ma ing an open head, a ysolid one was used. To the head 22 roduce-an integral head and they are simp y employed for the purpose of are attached a series of bearings 26 upon ywhich bearings aremounted the rollers 27,

said bearings and rollers being located concentrically with the inner'and outer rings 23 and 24. The cam-ring 2S is located within the'- space partially inclosed by the rollers 27,

and said ring being formed ofsueh a size that its periphery Will come in contact-with the perlpheries of all the rollers 27, thereby holdmg the cam-ring28 in proper relative osition with reference to the head 22 an esp ecially with reference to the concentricl rin 23 and 24.

l e mandrel 29 is composed of sections, which sections are provided with the spokes 30, which spokes are shaped ends 31, said we ge shaped ends bein formed of a size and shalpe to correspond wit the size and sha e of t e grooves 32 formed in the mandrel s aft or rod 33, said grooves gether b means o the turnbuckle 42, which 4 being for the purpose o f receiving the wedge shaped ends 31 located upon the spokes 30, thereby providing a means for producing a mandrel that is light, and at the same time have sufficient strength for the pu ose for which it is designed. To the hinge end of the mandrel proper is attached the collar 34, which collar is located upon the mandrel sections or mandrel proper 29 as best illustrated in Fig. 4. VThe collar 34 is provided with the bar 35 which is connected to the disk 36 in any convenient and Well known manner, said disk is adapted to rotate u onv the base plate 37.

rom whichplain round tapered skelps, a corrugated or uted pipe column or post is to be produced as hereinafter described. To the ead 22 are connected theradial bars 40 and Y.

41, said bars bein adjustably connected toturnbucl es are of the -usual construction and are connected to the bars 40 and 41 by the usual right and`left screw threads. The bars 40 are preferably provided with the anti-friction rollers 43 and the bars 41 are provided With the corrugating or fluting rollers 44. The anti-friction rollers 43 are located in contact with the faces of the cams 45, the faces of said cams being located at va tangent to a true circle described by the cam ring, the center of said cam rin being co-axial withthe mandrel when sai mandrel is bro ht into position for the coaction of sai mandrel With the corrugating head pro er.

' various cams as shown 'that the distance Ver from a common center is-varied in l pro or tion to the pitch and the length of eac o? the cam faces, by which arrangement the various bars 40 and 41 are permitted to reciprorovided with Wedgel It will e understoodthat by locating thesomm cate to and from a common center thereby movement of the bars 40 and '41, but this movementv is only ermitted as the bars are released as hereina ter described. The cam ring 28 is provided with a toothed segment or section `46, whichv toothed se ment or section meshes with the toothe se ment'47 said toothed segment being pivotal y mounted upon the stud 48, which stud is connected to the head 22. The segment 47 is provided with the bifurcated arm 49 which arm engages the rod 50 which rod is set at an an le 1 to the bars 3 and 4, and is so located for t e purpose of imparting an oscillatory 'movement to the segment 47 during the time the head 22 is moved back and forth along the mandrel. It Will be'understood that when the head 22 moves in one direction the cam ring 28 will be moved or oscillated in a given direction, and when the head 22 is moved in the opposite direction "along the mandrel the can ring 28 will be moved in the opposite direction; that is to say when the head 22 moves toward the hinged end of the mandrel, the'cam ring 28 Will be slowly rotated or oscillated and in the pro er direction to release'the bars 40 and41, t ereby vcompensating for the differentA diametersy of th tapered mandrel.

t will be understood that by providing the turnbuckles 42 the distance between the extreme or contact edges of theyanti-friction rollers 43 and the corrugating rollers 44 can be adjusted so that the proper pressure Will be brought upon the metal, and at the same time a limited adjustment may be given whereby' mandrels of dilerent sizes can be employed and the corrugatingrolls set-so as to properly act, but 4this a ustment just above pointed out is not depended upon en' tirely owing to the fact that different heads may be employed and should necessarily be employed where the difference in size is quite considerable', and difference in shape in cross section. In some instances it mi ht be ydesirable to'make a rectangularco umn or a column rof any other shape in section, in V which be employed, but in any event the limited adjustment should'be provided for so as to maintain the proper pressure under all circumstances, and at the same timeso adjust the various bars carrying the corrugatin rolls so that the pressure will be even in all event a different-shaped head should man radial lines. It is Well understood that if thel l rod 52, which rod is extended through the slotted bar 53 which slotted bar is secured to the standard 2. It will be understood that when the mandrel is'moved in-a horizontal in true parallelism with reference to\ each other, and in order to provide for the proper" y adjustment of the bearings the standard 2 is v plane and as it turns upon-a vertical center or the pivoted point fixed by the bolt 38 the cam faced ring 51 will be oscillated by reason of the rod 52 passing through the slotted bar 53; and a ainst the face of the ring 51 is located a s idable ring 54,- Which slidable ring has a cam face corres onding with thecam face of the ring 51 so t at when the cam ring 51 is rocked or oscillated the slid'able ring 54 will be moved a short distance upon the mandrel, thereby moving with it the finishedcolumn or pipe. It of course being understood that the end of the ip'e when moved must be and is against the ace or edge of the ring 54.- It therefore follows that When'the mandrel is swung in a horizontal ,plane the finished product will be moved endwise along the mandrel, thereby starting the finished product after which it 'can be easily removed in the usual manner. It will ybe understood that in order to prevent the carrying blocks from binding as they are m'oved back and forth along the A screw threaded shafts 14 and 15, said screw threaded shafts mustA be set provided with the rectangular flange 55,

. which rectangular fiange is for the purpose of i during providing a means for plroperl clamping the c partible boxes 56,'whi parti le boxes after they have been 'properly adjusted areheld bly means of the set-4 vscrews 57 and are c amped to the standard or standards 1 and 2 by means of the clam ing bolts 58.

It will be understood) that the a ertures formed in'the standards through W ich 'the screw threaded shafts are located should be of a greater diameter than the diameter of theshafts in order to provide for the limited adjustment necessary to bring thescrew threadedl shafts 14 `and 15 into vroper paral- 'lelisnL- The apertures 59 shou d also be of a greater diameter than the diameter ofthe bolts 58 so that said bolts can be free to vmove the time the adjustment of the boxes 56 is being made. A

It will be understood that there will bea pull and push strain upon the screw threaded shafts 14 and `15 durlngthe time the head and the different arts carried thereby is moved, and in or er to prevent anyl end movement of the screw threaded shafts, the

the corrugating or fluting rollers the fin-f vboxes 56 are set in the recessed or annular fia ed portion 60 of the screw threaded sha ts.

For the purpose of holding the cam ring 2S i.

against any lateral dis lacementthe ring 61 is rovided and is bo ted or otherwise attac ed to the head 22. A For the purpose of assisting in holding the -ends of the mandrel sections together at the free and of the mandrelproper the cap or collar 10 is provided.
